I took a decission regading light conditions (sun outside and dark shadows), thats why the outer part of the picture is whited out. I needed longer exposition so that the inner cave is in detailed view.
Will need to attemt this take later in different light conditions i think.

Old settlement from The Stone age, at that time the water level was almost up to the cavefloor.

This settlement was here in the late part of Stone Age appr. 8000-6000 years ago. This cave was ... the first found in norway of this type, and it has been checked by archaelogists 4 times in 1907,1910,1939 and in 1941.

a skeletal was found dated appr. to 7500 years ago. Some of the findings can be seen at the museum of Stavanger.
